Why Do Humans Have Earlobes? An Evolutionary Biologist Explains
Earlobe's biological function remains a mystery, with current research suggesting it may be an evolutionary remnant rather than serving a significant purpose. While some theories propose thermoregulation or sensory roles, these are largely unsubstantiated. Evolutionary biologists posit that earlobes might persist due to genetic drift or as a developmental byproduct, a concept known as a spandrel, rather than through direct natural selection for a specific function.
